Before there's any chance getting working camera the Fully Interactive Mobile Camera Imaging Subsystem (FIMC-IS) driver needs to be extended to support exynos5. An old patchset for this that was never merged exists: https://lore.kernel.org/all/1383653610-11835-1-git-send-email-arun.kk@samsung.com/ (v12 seems to be latest sent version). Y Y Y Y Y Y N N N N
